The work of developing International Standards is carried out through IsO Technical Committees. Every Member Body interested in a subject for which a Technical Committee has been set up has the right to be represented on that Committee. International organizations, governmental and non-governmental, in iiaison with IsO, aiso take part in the work. Draft International Standards adopted by the Technicat Committees are circulated to the Member Bodies for approvat before their acceptance as International Standards by the ISO Council. Standard ISO 1966 was drawn up by Technical International Committee ISO/TC 20, Aircraft and space vehicles. It was approved in May 1970 by the Member Bodies of the following countries : India Belgium South Africa, Rep. of Brazil Israel Spain Italy Switzerland Canada Czechoslovakia Japan Turkey Egypt, Arab Rep. of Netherlands United Kingdom Germany U.S.S.R.
